Drainage system of municipal solid waste landfill

Abstract

The invention discloses a drainage system of a municipal solid waste landfill. The drainage system of the municipal solid waste landfill comprises one or two clean water ditches which is / are disposedon one side or two sides of a waste pile and a sewage ditch which is disposed at the bottom of the waste pile, wherein the clean water ditch is composed of a concrete bottom surface and brick buildingbodies which are disposed on the two sides of the concrete bottom surface; the top surface of the waste pile is a slope surface; the upper end surface of one brick building body is jointed with the lowest point of the slope surface; continuous HDPE film is paved on the slope surface and on the side walls and the bottom wall of the clean water ditch, the sewage ditch is located below the concretebottom surface; and sand gravels or pebbles are paved in the sewage ditch. By means of the drainage system of the municipal solid waste landfill, clean water is effectively separated from sewage, thesituation that the clean water enters the pile and consequently the load of the pile is increased is eliminated, the stability of the landfill pile is guaranteed, the situation that the clean water enters the waste pile and becomes sewage is reduced, and the clean water and sewage are drained through the corresponding ditches.

Description

technical field [0001] The invention relates to the technical field of domestic waste landfill, in particular to a drainage system for domestic waste landfill. Background technique [0002] In recent years, with the acceleration of urbanization, the scale of cities has become larger and larger, and the urban population has also continued to increase. Suburban landfills With the increase of population, the suburban landfills are getting closer and closer to urban areas, and the problems of air and water quality involved are becoming more and more prominent. At the same time, the increase in the amount of garbage is also constantly bringing enormous pressure to urban development. Under this new form, continuous optimization of the process and technology of the landfill site has become an urgent problem for the current urban municipal management department. [0003] Many existing domestic waste landfills have simple management and simple landfill procedures. In the landfill ...

AI Technical Summary

Problems solved by technology

In the landfill process, due to technical defects, clear water enters the garbage dump in rainy days, and the sewage flows across, polluting the environment. If things go on like this, there will be more liquid inside the garbage dump, which will eventually lead to the instability of the garbage dump and localized garbage collapse. ACCIDENT
